In the upcoming release of Godot 4.3 (currently in Beta1) there is a massive change to the TileMap class.  Well, it's dead, or more accurately deprecated and will have no further development from this point on.  Instead it is replaced with a more streamlined replacement, the TileLayer node.  We will look at how to create Tilemaps using the new system in Godot 4.3 and discuss the pros and cons of this change.

Godot 4.3 introduces a significant change in how tile maps are handled, replacing the old TileMap system with TileMapLayers. TileMapLayers offer a more logical and streamlined structure but require separate configurations for each layer. While this new setup is cleaner, the inability to share tile sets across layers might be a downside. Existing TileMap is now deprecated but can still be used with no future updates. Developers will need to port their code to the new system for future compatibility.

Godot Tile Maps Are Dead ...Long Live TileMapLayers

<p>You can share tilesets by simply duplicating the TilemapLayer, and it will have the same tileset, and if you update the tileset on one of the layers, it will update it on all of them.</p>
